Abstract

A belt-type CVT is comprised of a driving pulley (10) and a driven pulley (20) each of which has having a transmission piston chamber (12,22) and a clamp piston chamber (9,19). An effective cross sectional area of the driving-side clamp piston chamber is equal to an effective cross sectional area of the driven-side clamp piston chamber. The driving-side clamp piston chamber is fluidly communicated with the driven-side clamp piston chamber through a common passage.
